When the wet brake brakes, high-pressure oil of a brake system enters a piston cavity of the wet brake, and a piston moves to press a dynamic friction plate and a static friction plate under the action of the oil pressure. The wheel-side space required by the special structure of the wet brake is large, so that all parts such as a wheel hub, a wheel-side reducer, the wet brake and the like need to be disassembled during maintenance, the disassembly and the assembly are difficult, and the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
According to the not enough of above prior art, the utility model provides a harbour is with AIT steering drive axle hydraulic disc formula arresting gear adopts hydraulic disc brake to solve the not enough problem in wheel limit space, has solved wet brake maintenance difficulty simultaneously, problem with high costs.
A harbour is with AIT steering drive axle hydraulic disc formula arresting gear, its characterized in that: the hydraulic disc type braking device is provided with two groups, and is symmetrically arranged on wheel edge assemblies at two ends of a steering drive axle, and comprises a braking disc, a fixed plate and two hydraulic disc type brakes; the outer periphery of the hub of the wheel edge assembly is sleeved with the brake disc and connected through splines, the outer periphery of the steering knuckle of the wheel edge assembly is sleeved with the fixing plate and fixedly connected through bolts, the two hydraulic disc brakes are symmetrically arranged on the outer side face of the fixing plate through bolts, and the hydraulic disc brakes are matched with the brake disc.
Furthermore, the fixing plate is of a circular ring structure. Preferably, the two hydraulic disc brakes are symmetrically mounted on the middle upper end of the outer side surface of the fixed plate through bolts. Preferably, the bottom of the fixing plate is provided with a notch, so that the effects of saving materials and reducing weight are achieved.
Furthermore, the hydraulic disc brake adopts a hydraulic caliper disc brake, friction plates are symmetrically arranged in a shell of the hydraulic disc brake, a pin shaft is arranged between the two friction plates and the shell in series, a cotter pin is installed at one end of the pin shaft, and an opening is formed in the outer circumferential surface of the shell of the hydraulic disc brake. This patent is based on hydraulic pressure tong disc brake among the prior art and is done the upgrading transformation, firstly fixes two friction discs and casing through the round pin axle, has secondly increased the opening design. When the friction plate is replaced, only the pin shaft needs to be taken down, the friction plate can be taken out from the opening to be replaced, the hydraulic disc brake does not need to be detached, and the maintenance is simple and convenient. The working principle is the same as that of a hydraulic caliper disc brake in the prior art, namely, high-pressure oil enters a piston cavity of the hydraulic disc brake, and under the action of the oil pressure, the piston moves to enable two friction plates to tightly press a brake disc positioned in the middle, so that braking is realized.
The utility model discloses the beneficial effect who has is: (1) the hydraulic disc brake is adopted, the required space is small, and the problem that the wheel side space of an AIT steering drive axle is insufficient can be solved; (2) two hydraulic disc brakes are symmetrically installed, the braking force jointly played can meet the design requirement, and the problem of insufficient braking force of the hydraulic disc brakes is solved; (3) the hydraulic disc brake can be used for replacing the friction plate independently, and the friction plate can be taken out for replacement only by taking down the pin shaft; meanwhile, when the hydraulic disc brake needs to be replaced, the hydraulic disc brake can be replaced only by detaching the bolts without detaching parts such as the wheel hub and the hub reduction assembly, and the maintenance cost is low.
