Independent steering system driven by motor

Abstract: The utility model discloses an independent steering system driven by a motor, which belongs to the steering technical field of heavy transportation facilities. The system comprises a hydraulic variable pump, a slewing bearing, an angle sensor, a hydraulic motor, a controller, a proportional multiway valve, an overflow valve and a hydraulic oil tank; the hydraulic variable pump is respectively connected with the hydraulic oil tank and the proportional multiway valve; the proportional multiway valve is respectively connected with the hydraulic motor and the controller; the hydraulic motor is respectively connected with the slewing bearing and the hydraulic oil tank; the angle sensor is connected with the slewing bearing; and the overflow valve is respectively connected with the hydraulic variable pump and the proportional multiway valve. The independent steering system drives the slewing bearing to steer through the hydraulic motor, thereby solving the problems of complex multi-mode steering operation and difficult arrangement of large-tonnage engineering vehicles, improving the accuracy of the steering angle of the large-tonnage engineering vehicles and reducing the complexity of the structure of the steering system.

Composite slewing bearing

Abstract: The utility model provides a composite slewing bearing. The bearing comprises a central slewing bearing (104) and peripheral bearings arranged around the central slewing bearing, wherein the central slewing bearing comprises first slewing parts (106), second slewing parts (107) and a plurality of rollers (108); the second slewing parts surround the first slewing parts; containing space is formed between the peripheral surfaces of the first slewing parts and the inner surfaces of the second slewing parts; the plurality of rollers are installed in the containing space; and the peripheral surfaces of the second slewing parts are toothless. The composite slewing bearing can be applied on the front one of two crawler cranes carrying out joint operation and can provide huge support force and side tumbling resistance to the upper vehicle of the front crawler crane, thus ensuring the cranes to have better operation stability and safety during large operation.

Vertical type driving mechanism for laser-guiding automatic guided vehicle (AGV) forklift

Abstract: A vertical type driving mechanism for a laser-guiding automatic guided vehicle (AGV) forklift comprises a driving mounting plate, a driven gear, a traveling motor and a steering motor. A slewing bearing is fixedly arranged on the lower surface of the driving mounting plate, the traveling motor is fixed to the upper end of the slewing bearing, and a reduction case is arranged at the lower end of the slewing bearing. A motor shaft of the traveling motor is arranged downwards and is inserted into the reduction case at the lower end from the upper end of the driving mounting plate, and a shaft sleeve is arranged outside the motor shaft and arranged in the reduction case; a driving gear is arranged at the bottom of the reduction case and connected with a first bevel gear inserted into the reduction case, the end of the motor shaft is connected with a second bevel gear through a gear train, and the first bevel gear and the second bevel gear are engaged; the driven gear is fixed at the upper end of the reduction case, the steering motor is inversely fixed to the driving mounting plate, and a steering gear is arranged at the end of the steering motor and engaged with the driven gear.

Fork truck rotary lifting support accessory

Abstract: The utility model discloses a fork truck rotary lifting support accessory, comprising forks fixed on a rotary support, which is connected to a back plate of a lifting support through a slewing bearing; an inner ring bearing of the slewing bearing is in fixed connection with the rotary support; an outer ring bearing of the slewing bearing is in fixed connection with the lifting support; the inner ring bearing is driven by a hydraulic motor, which is fixed on the back plate of the lifting support; the rotary support is provided with a folk stringing shaft; and one end of each folk is sleeved on the folk stringing shaft. The fork truck rotary lifting support accessory is widely applicable to industries, such as foodstuff, automatic production, chemical industry, recycle, smelting and casting, and to occasions where rotary roll-over and stirring of hoppers or boxes are required.
