Abstract
The invention provides a vehicle height adjusting device which comprises a spring base component and an adjusting shaft, wherein the spring base component is supported on a wheel-side component and provided with a spiral spring with a small-diameter thread part, and the adjusting shaft is spirally combined with the spring base component; the bottom of the spring base component is integrally formed into a bolt body; the adjusting shaft is spirally combined on the bolt body at the bottom of the spring base component, and an outer hexagon is arranged at the lower end of the spring base component; adjusting cushion blocks with corresponding specifications are arranged between the spring base component and the wheel-side component and used for adjusting the vehicle weight; an adjusting sleeve is sleeved outside the adjusting shaft; an outer hexagon is arranged at the lower end of the adjusting shaft; and a flange face which is supported on a step face inside the adjusting sleeve is formed at the lower end of the adjusting shaft. By arranging various specifications of adjusting cushion blocks, the invention improves the adjusting range of the whole vehicle weight; and as main stress points in the structure are not positioned in the thread part any more, the invention increases the mechanism reliability, reduces the thread failure probability, prolongs the service life of the mechanism and accelerates the assembly process.
Description
Technical field
The present invention relates to a kind of adjusting apparatus for height of vehicle, the especially a kind of device that can when the both sides overall height does not wait, regulate.
Background technology
Traditional adjusting apparatus for height of vehicle utilizes spring lower seat (negative thread) to be spirally connected with regulating bolt (outside thread), and the rotation adjustable screw causes the spring lower seat longitudinal travel, thereby makes bodywork height change, and reaches overall height and regulates purpose.There is following defective in traditional adjusting apparatus for height of vehicle: 1, impacting with screw thread supporting reverse load, is gapped owing to be threaded, and in being subjected to the reverse load impact process for a long time, can cause screw thread impaired, can't regulate, even cause losing efficacy.2, after carrying out big height adjustment, screwing length is short between spring perch parts and the adjusting bolt, causes the screw strength deficiency easily, causes thread failure and causes the enforcement performance to reduce, and causes safety misadventure; 3, because the stressed threaded portion that is mainly of such device behind the vehicle long-play, easily causes overall height to regulate difficulty, reduce service life.
Summary of the invention
The objective of the invention is to: the structure to traditional adjusting apparatus for height of vehicle is improved, and provides a kind of and improves car load overall height setting range, increases mechanism reliability, prolongs mechanism's adjusting apparatus for height of vehicle in service life.
The adjusting shaft that the present invention is screwed by the helical spring spring lower seat parts that are supported on the threaded portion, the thin footpath of band on the wheel-side member, with these spring lower seat parts constitutes, the spring lower seat feature bottom is one-body molded to be the body of bolt, adjusting shaft is screwed together on the body of bolt of spring lower seat feature bottom, the lower end has outer-hexagonal, the adjusting cushion block of corresponding specification is set, in order to regulate overall height between spring lower seat parts and wheel-side member.
Adjusting shaft of the present invention is with regulating sleeve outward.The adjusting shaft lower end has outer-hexagonal.The adjusting shaft lower end forms the flange face that is supported on regulating sleeve interior step face
The integrated bolt body of spring lower seat feature bottom of the present invention outside thread matches with the adjusting shaft negative thread.
The present invention possesses following characteristics: 1, regulate cushion block by placing all size, improved car load overall height setting range; 2, pass through the spring lower seat member supporting on body part or adjusting cushion block, the main stress point of structure no longer is a threaded portion, has increased mechanism reliability; 3, overall height is regulated and mainly to be regulated cushion block by placing all size, and is the main stress point of overall height regulating mechanism, has reduced the probability of thread failure, has prolonged mechanism service life.4, reduced by a part, accelerated fitting process.
Description of drawings
Fig. 1 is a cross-sectional view of the present invention;
Fig. 2 is each component mounting structure scheme drawing of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
The adjusting shaft 3 that the present invention is screwed by the spring lower seat parts 1 of the coil spring 5 that is supported on the threaded portion, the thin footpath of band on the wheel-side member 2, with these spring lower seat parts 1 constitutes.Spring lower seat parts 1 bottom is one-body molded to be the body of bolt, and adjusting shaft 3 is screwed together on the body of bolt of spring lower seat parts 1 bottom, and the lower end has outer-hexagonal, but the serviceable tool rotation is carried out overall height and regulated.2 of spring lower seat parts 1 and wheel-side member are provided with the adjusting cushion block 2 of corresponding specification, in order to regulate overall height.Spring lower seat parts 1 bottom integrated bolt body outside thread matches with adjusting shaft 3 negative threads.The adjusting shaft 3 outer regulating sleeves 4 that are with, adjusting shaft 3 lower ends form the flange face that is supported on regulating sleeve 4 interior step faces.
The present invention can utilize outside adjustment means to regulate the overall height that does not wait the wheel both sides, the spring lower seat parts are limited its rotation by wheel-side member, make the spring lower seat parts produce displacement along with the adjustment means rotation along axis of thread direction, add the adjusting cushion block of corresponding specification then in the gap between wheel-side member and spring lower seat parts, regulate the overall height purpose in order to reach.
