Description
Technical Field
The utility model relates to an automobile recirculating ball hydraulic power steering gear.
Background
In the design of the whole vehicle, when a vehicle with a higher cab exists, the universal joint of the steering column is limited by the structure of the engine room, the input shaft of the original platform vehicle-type steering gear needs to be lengthened, the input shaft of the steering gear is directly lengthened, the rigidity is poor, and the oil leakage risk of an input shaft oil seal is increased.
Disclosure of Invention
An object of the utility model is to provide a lengthened axle assembly for circulating ball hydraulic power steering gear, it can be applicable to the higher motorcycle type in driver's cabin with current steering gear lug connection back.
In order to achieve the above purpose, the technical scheme of the utility model is that:
the lengthened shaft assembly for the circulating ball hydraulic power steering gear comprises a shaft supporting seat, a lengthened shaft, a self-aligning bearing, a clamp spring, a dust seal, an upper cover and an O-shaped sealing ring; the axle supporting seat is the step type, the axle supporting seat has an inner hole, its inner hole matches with the axial excircle, there is the extension axle in the axle supporting seat inner hole, aligning bearing, the jump ring, there are aligning bearing and jump ring in the rear end outside of extension axle, the dust seal, aligning bearing will add the extension axle and fix in the axle supporting seat, the jump ring restriction extension axial displacement, there is the dust seal in the upper cover, the dust seal will add the extension axle and seal, the upper cover stretches into in the tip of axle supporting seat and is connected with the tip of axle supporting seat, there is the internal spline with steering gear external splines assorted in the front end of extension axle, there are two O type sealing washers in the terminal surface of axle supporting seat tip.
The utility model discloses an actively the effect does:
1. the utility model is suitable for the higher motorcycle type of driver's cabin, need not redesign the diverter just can satisfy the demand of whole car;
2. the lengthened shaft of the lengthened shaft assembly is connected with the outer spline of the steering gear through the inner spline, and the structure is simple and the process is good.
