Independent suspensions for lowering height of vehicle frame

Abstract: A modular independent coil spring suspension for steerable and non-steerable wheel assemblies and driven and non-driven axles. The suspension is of the general type in which each wheel has an upper and a lower control arm, and a single coil spring secured between the lower of the two control arms and the chassis. The upper and lower control arms each have inner ends split into two segments, each of which is connected to the vehicle frame by a special bushing assembly. The suspension has a novel upper control arm which is split into two segments, each segment being bent to accommodate an edge of the frame of the vehicle, thereby allowing the frame of the vehicle to be mounted lower with respect to the wheel assemblies.

Counter balanced suspension

Abstract: A vehicle suspension system (110) having a primary suspension system (112) and a secondary suspension system (114). Vertical motion of a vehicle wheel (120) places a force on the vehicle frame (126) which, in turn, places a force on the vehicle body (124). The secondary suspension system (114) translates the relative motion between the wheel (120) and frame (126) into a force on the vehicle body (124) which is equal and opposite to the force transmitted from the frame (126) to the body (124). A frictional shock absorber (300) is utilized in the suspension system (110) as well as a multi-stage coil spring (400).

Motorised trench digger, e.g. for laying cables or pipes

Abstract: The trench digger has a tracked vehicle (1) with a chassis (2) and a frame (4) supporting an engine and a cab. A digging unit (5) is towed by the vehicle and connected to it by a coupling system (6). The vehicle has an alignment mechanism (8) which turns the vehicle frame to one side if the digger unit moves to one side of the vehicle. The alignment mechanism maintains the centre of gravity of the vehicle in line with its lengthwise median plane. The alignment mechanism has a toothed wheel (9) meshing with the pinion (11) of a reduction gear unit. A second pivoting member (13) is situated between the chassis and frame to turn the frame relative to the chassis. The second pivoting mechanism incorporates a crown wheel linked to the frame and chassis through bearings and operated by power cylinders.

Auxiliary frame for goods vehicle, particularly one equipped with crane

Abstract: The frame has two part profiles (5a,5b). One (5a) can be fitted on top of the vehicle's main frame (1) and the other (5b) under. Both parts, with the aid of extending and overlapping tabs (8,10,12,17), can screw to one another and between them leave free recesses (18) for cross bearers (3) on the vehicle frame. The upper part is preferably formed from a hollow profile (6) and the lower from bearers (9) of L- or T-shaped cross-section. The tabs may be joined to one another by screws (11) and run within the vehicle main frame.

Ultra-mini automobile

Abstract: The utility model relates to an ultra-mini automobile. The skeleton of a vehicle body is composed of a platform vehicle frame and front and rear security protection frames and an upper security protection frame welded on the platform vehicle frame; the front part of the skeleton of the vehicle body is provided with a front wall shell and a front air window with a large curved surface, and the rear part of the skeleton of the vehicle body is provided with a rear wall shell and a rear air window; a curly wing type door is arranged on the upper security protection frame by a hinge, and then the vehicle body is formed. A suspension frame mechanism and a speed-change mechanism are arranged on the platform vehicle frame. A manipulator handle provided with a start button, a rocking arm for throttle control, a horn button, the push-button switch of a car lamp, the push-button switch of the conversion of far and near light lamps and the switch of a turn lamp is adopted to control the ultra-mini automobile to turn, brake and accelerate to finish all drive and operation actions. The utility model is especially suited to be driven by a person whose lower limbs are disabled.

Track laying vehicle used for loading by tipper

Abstract: The vehicle runs on two pairs of tracks. Each pair is mounted on the vehicle frame in such a way that it can be pivoted about a vertical axis. The vehicle frame consists of two rigid halves which are elastically interconnected by torsion bars. The angular positions of the pairs of tracks can be observed by the driver of the vehicle on a monitor in the driver's cab. Required corrections can be carried out automatically. The driver's cab protrudes above and to the side of the load space. A pivoting mirror is mounted opposite the driver's cab.

Low-height double-deck bus

Abstract: The utility model relates to a low-height double-deck bus. The transverse beam of an upper layer vehicle body is equipped with a main beam in the form of crossing, and the up-down of the sliding roof of the upper layer vehicle is controlled by an inferior hydraulic cylinder. A hoist trunk hydraulic cylinder is positioned on a main vehicle frame, and frames of the upper and lower layer vehicles are positioned on the vehicle body. A front pillar is equipped on the upper layer vehicle, and a damping spring and an air buffer are fixed beneath a lower camber beam of a front sedan. The lower layer and upper layer of the vehicle body are evenly equipped with longitudinal frames, and rear vehicle frame is higher than the main vehicle frame, so that the installation of the buffer frame and rear wheels is convenient. The path of the back door is against the back row seats on a steel plate, steps are arranged at the bottom of a vehicle door, and pillars are positioned at both sides of staircases. The utility model can reduce gravity center and increase speed of a motor vehicle.

Multi-purpose push-pull vehicle

Abstract: The utility model belongs to man powered push-pull vehicles, comprising a drawing frame, a vehicle frame, a front wheel and a back wheel. The vehicle frame is a frame on which is provided with a transverse beam protruding towards the ground, the two side beams of the frame are respectively hinged with the cover plate of the frame, and the drawing frame is hinged on the vehicle frame. The utility model can conveniently transport liquefied gas bottles and can be served as a flat car. The structure is simple, the push and the pull are flexible, the transportation of objects is convenient, and the utility model can be folded. The man powered push-pull vehicle is suitable for the use of the household shopping, the food purchase and the coal gas exchanging.

Wind-proof and rain-proof vehicle for disabled person

Abstract: The utility model belongs to wind-proof and rain-proof walk-substituting vehicle for disabled person, which is characterized in that the closed carriage is adopted for wind proof, rain proof and sun shielding, and a rear wheel is hung solely; an engine adopting driving shaft and gear transmission is up-side-down arranged on the vehicle frame at the rear part. Improved on the structure, the utility model has the advantages of simple structure, wind proof, rain proof, small volume, lower barycenter and good vibration damping performance.

Device for driving electric vehicle

Abstract: The utility model relates to a device for driving electric vehicles, comprising a DC motor and a gear speed reducer. The utility model is characterized in that the DC motor and the gear speed reducer are connected with a screw bolt (3) as a whole by a speed reducer seat (1). The speed reducer seat (1) is provided with a notch (A) and an installing frame (B).
