Abstract
The utility model provides a rack-and-pinion type steering gear, which is applied for the technology field of components of a motor vehicle steering system. The rack-and-pinion type steering gear comprises a steering gear housing (1) and a steering gear oil cylinder (2). The steering gear housing (1) is integrated with the steering gear oil cylinder (2); the steering gear housing (1) and the steering gear oil cylinder (2) are prepared from cast aluminium; and the form and location tolerances such as coaxiality and circularity of the steering gear are all completely guaranteed. According to the steering gear, the steering resistance is substantially reduced, the operation stability in steering is raised, the hand feeling and the comfort level of a driver are obviously raised. The steering gear is prepared from cast aluminium, which substantially reduces the matching weight requirement of the steering gear on a hole vehicle, the surface of the steering gear requires no special processing to satisfy the requirement.
Description
Technical field
The utility model belongs to motor vehicle steering system parts technical field, more particularly, relates to a kind of rack and pinion steering gear.
Background technology
At present, a lot of hydraulic power steering device of the prior art, mechanical type deflector, all adopt the structure of housing together with being fitted in oil cylinder, simultaneously by pressing so that housing and oil cylinder fix, housing and oil cylinder pull when preventing hypertonia, cause the Problem of Failure such as leakage of oil.Existing deflector, housing generally adopts casting aluminium material, and oil cylinder adopts 20# steel or 45# steel.After together with steering gear housing is fitted in deflector oil cylinder, easily cause the coaxiality deviation between steering gear housing and deflector oil cylinder, so that turn to feel to lay particular stress in car load coupling, and easily cause steering gear housing and oil cylinder to pull when press-fiting, pressing, waste man-hour etc.
Utility model content
Technical problem to be solved in the utility model is: for deficiency of the prior art, provide a kind of simple in structure, can reduce the coaxiality deviation between steering gear housing and deflector oil cylinder, thereby greatly reduce cornering resistance, improve the rack and pinion steering gear of the handling stability energy of deflector.
Solve above-described technical matters, the technical scheme that the utility model is taked is:
The utility model is a kind of rack and pinion steering gear, comprises steering gear housing, deflector oil cylinder, and described steering gear housing and deflector oil cylinder are set to integral structure, and steering gear housing and deflector oil cylinder are cast and are processed by casting aluminium material.
Preferably, described deflector oil cylinder inside arranges bearing position, oil sealing position, and described bearing position and oil sealing position are set to cast the structure of processing together with casting processing steering gear housing is during with deflector oil cylinder.
Preferably, the both ends of described deflector oil cylinder inside respectively arrange an oil sealing position, and it is inner that hydraulic piston is arranged on deflector oil cylinder, and hydraulic piston is set to the structure between two oil sealing positions.
Adopt the technical solution of the utility model, can obtain following beneficial effect:
Rack and pinion steering gear described in the utility model, steering gear housing and deflector oil cylinder are set to integral structure, and steering gear housing and deflector oil cylinder material are cast aluminium.The bearing position of the deflector oil cylinder inside of whole deflector, oil sealing position are all with steering gear housing and deflector oil cylinder is disposable processes, and by such structure, some form and position tolerances such as the right alignment of deflector, circularity, all can guarantee completely.Deflector of the present utility model, matches at car load steering swivel system, can greatly reduce the cornering resistance of deflector, improve the handling stability energy while turning to, feel, the comfort level of chaufeur are significantly improved, in a word, have met preferably the requirement on in-use performance.The material that the utility model adopts is cast aluminium, also greatly reduces the weight requirement that deflector matches at car load, and its surface also, without carrying out special processing, just can meet the demands.
Accompanying drawing explanation
The expressed content of each accompanying drawing of this specification sheets and the mark in figure are made to brief description below:
