Description
Technical field
The utility model relates to the angular adjustment apparatus that a kind of vehicle steering is used, particularly a kind of adjustable tilt angle device for steering column of car that can carry out angular adjustment and reliable location to the steering shaft of the steering column of fixed-direction dish.It both had been applicable to various car and passenger vehicle, also be applicable to heavily, in, light-duty truck, also can be used for all kinds self-propelled vehicle that other has bearing circle.
Background technology
At present, most of automobiles and have the steering column of the self-propelled vehicle of bearing circle can not carry out angular adjustment, the navigating mate of different heights are difficult to adapt to, and feel very uncomfortable, especially long-distance driving is easy to cause the navigating mate fatigue driving, can produce hidden peril of accident.For overcoming the defective that above-mentioned vehicle steering exists, common method of adjustment is that the steering shaft with steering column carries out suitable adjusting angle, to adapt to the needs of navigating mate.Part great majority such as the swinging mounting body of existing adjustable steering column are the section bar welded structure, and its member is more, the manufacturing process more complicated, and working accuracy is on the low side, and the form and position tolerance that the member welding deformation causes is bigger, and yield rate is lower.Therefore, this has not only increased manufacturing cost, and has reduced the assembly precision of parts, is difficult to guarantee the accurate reliability of steering column adjusting location.In addition, the critical component location locking mechanism that steering column changes the inclination angle adopts thread lock, and it is very hard to regulate operation, and manipulation is very inconvenient, obviously reduces its in-use performance and service life.
The utility model content
The purpose of this utility model provides a kind of adjustable tilt angle device for steering column of car, it has fundamentally changed the manufacturing deficiency that prior art exists, reasonable in design, significantly improve working accuracy, easy to adjust, accurate positioning is handled laborsaving, be easy to satisfy navigating mate comformability and traveling comfort requirement, safe and reliable, the life-span is long, and is applied widely.
The purpose of this utility model is achieved in that this device comprises band combined switch adapter plate, the swinging mounting body of spring-hanging board and assemble last steering shaft in it, support the fixed support of turning rack body and assemble its interior following steering shaft, on hinged, the universal-joint of following steering shaft, location locking mechanism and handle trim mechanisms, its technical essential is: described swinging mounting body is for adopting the member of die cast metal moulding, the axle bed of swinging mounting body and support bracket fastened axle bed are hinged by adapter shaft, described location locking mechanism adopts intermeshing ratchet and cam detents positioning and locking, the upper end of cam detents is hinged on the journal stirrup of swinging mounting body by straight pin, the lower end of cam detents is pressed on the ratchet by locking plate, locking plate two ends engaging lug with the interlock of the push rod of handle trim mechanisms, be hinged between swinging mounting body and the fixed support by adapter shaft, locking plate moves back and forth around the cam contact surface of adapter shaft along cam detents, drives the cam detents disengaging or compresses ratchet.
Described swinging mounting axon seat and the hinged adapter shaft of fixed support axle bed are adopted threaded bearing pin, the thread end of adapter shaft is fixed on the axle bed of swinging mounting body by nut.
The described ratchet that is meshed with cam detents is arranged on the fixed bearing top by collar supports.
The push rod the other end described and handle trim mechanisms that locking plate links is movably connected in to be adjusted on the link rod, adjusts link rod is hinged on the swinging mounting body by pivot pin a side.
The lower end of described cam detents is pressed on the ratchet by the locking plate of the tension of the back-moving spring on the spring-hanging board of swinging mounting body.
Because the location locking mechanism of intermeshing ratchet and cam detents is adopted in steering column of the present utility model inclination angle adjustment, angle to car steering tube column is suitably carried out positioning and locking after the adjustment, so compare with the location locking mechanism of thread lock, reasonable in design, safe and reliable, the life-span is long.It has fundamentally changed the manufacturing deficiency that existing thread lock mechanism exists, its swinging mounting body adopts the member of die cast metal moulding, adopts intermeshing ratchet and cam detents positioning and locking, and the anufacturability of member is good, significantly improve working accuracy, form and position tolerance is less.Therefore, the yield rate height of member, this has not only reduced manufacturing cost, and has improved the assembly precision of parts.Bar handle, the interlock push rod drives the locking plate that is pressed on the cam detents, moves back and forth around the cam contact surface of adapter shaft along cam detents, drives the cam detents disengaging or compresses ratchet, makes adjusted swinging mounting body and fixed support location and locking.Its easy to adjust, accurate positioning is handled laborsavingly, when guaranteeing that steering column is regulated the accurate reliability of location, has also satisfied navigating mate comformability and traveling comfort requirement at an easy rate.Because of it both had been applicable to various car and passenger vehicle, also be applicable to heavily, in, light-duty truck, also can be used for all kinds self-propelled vehicle that other has bearing circle, so applied widely.
