Abstract
The utility model provides a balanced suspension and steel plate spring connecting device which comprises a balance bearing hub, a steel plate spring, four U-shaped bolts, a bolt cover board and nuts. The bolt cover board and the nuts are positioned above the steel plate spring. The balanced suspension and steel plate spring connecting device is characterized in that two grooves are symmetrically arranged at both sides of the lower surface of the balance bearing hub; the four U-shaped bolts are divided into two groups and the two groups of U-shaped bolts are symmetrically surrounded the grooves in the balance bearing hub; both ends of the U-shaped bolts pass through peripheral bolt holes in the bolt cover board in a diagonal-tension upward-passing mode to be fastened with the nuts; and the diagonal tension angle for the diagonal-tension upward-passing is in the range of 12 to 16 degrees. According to the utility model, the nuts are arranged above the plate spring and are convenient for assembly and maintenance of an assembly; and due to the variation of a connecting mode, a spacing between a tire and a balance shaft is increased, so that when the large-scale tire is adopted, the sufficiently large spacing can be ensured and the normal running and operating of a heavy duty truck are ensured.
Description
Technical field
The utility model relates to a kind of automobile balance suspension and steel spring connecting device.
Background technology
At present the bearing hub in the used balance suspension assembly of bogie with steel plate bullet connection structure is: with 4 vertical from the top down U-bolt holes of passing leaf spring cover plate, steel spring and bearing hub of U-bolt, fastening with thick hexagonnut on the plane below the bearing hub.
The problem that exists is:
1, bogie is when keeping in repair parts such as maybe need changing bearing hub, leaf spring or U-bolt, because thick hexagonnut below bearing hub, need serviceable tool from following operation, and bearing hub is nearer apart from ground, makes maintenance operation inconvenience and efficient not high;
2, when bogie uses conventional tire, the tire inboard is 25～35mm with bearing hub side spacing, in the time of need adopting the tire of bigger specification because of the market demand; Because the increase of tyre width (or diameter); Tire is inboard to reduce 10～15mm with the bearing hub side play, at turn inside diameter or road not at ordinary times, increases bearing hub and produces the probability of interference with tire; Can damage tire when serious, vehicle can't be used.
Summary of the invention
For ease of assembling, keep in repair and satisfying the demand that oversize tyre is adopted in market, the utility model proposes a kind of balance suspension and steel spring connecting device.
The technical scheme of the utility model is: a kind of balance suspension and steel spring connecting device; Comprise equalizer bearing hub, steel spring, four clevis bolts, bolt cover plate, nut; Bolt cover plate and nut are positioned at the steel spring top, and it is characterized in that: the lower surface bilateral symmetry of equalizer bearing hub is provided with two grooves, and four clevis bolts are divided into two groups; Symmetry is encircled the groove on the equalizer bearing hub, and is fastening tiltedly to pull on the peripheral bolt hole and the nut that pass on the bolt cover plate at the form two ends of wearing; Tiltedly pull on wear the angle of tiltedly drawing be 12-16 °.
Beneficial effect: the U-bolt of the utility model is fastening with leaf spring and the connection of balance bearing hub tiltedly to pull on the form of wearing, and this form effectively reduces the bearing hub width, back axle tire and bearing hub spacing in the increase; When assembly was assemblied on the car load, nut was convenient to assembly assembling and maintenance above leaf spring.Since the variation of type of attachment, the former plane cancellation that is used for fastening U-bolt on the equalizer bearing hub, and tire and balance shaft spacing have increased, and when adopting oversize tyre, can guarantee enough big spacing, make bogie cruising and operation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure a kind of balance suspension and steel spring connecting device; Comprise equalizer bearing hub 2, steel spring 3, four clevis bolts 1, bolt cover plate 4, nut 5; Bolt cover plate 4 and nut 5 are positioned at the steel spring top, and the lower surface bilateral symmetry of equalizer bearing hub is provided with two grooves, and four clevis bolts 1 are divided into two groups; Symmetry is encircled the groove on the equalizer bearing hub, and is fastening tiltedly to pull on the peripheral bolt hole and the nut that pass on the bolt cover plate at the form two ends of wearing.Said tiltedly pull on wear the angle of tiltedly drawing be generally 12-16 °.
