Abstract
The utility model discloses an anti-loosening and anti-rotation hinge pin device, which comprises a hinge pin, wherein a check block groove is formed at one end of the outer side of the hinge pin, and is positioned in the transverse section of the hinge pin; a check block is arranged in the check block groove, and is provided with a connecting hole. By adopting the anti-loosening and anti-rotation hinge pin device, a wheel is prevented from coming off and rotating by a large angle while jumping and rotating on the premise of ensuring effective connection, wear between the hinge pin and an elastic element is reduced greatly, and the reliability of a system is improved.
Description
Technical field
The utility model relates to a kind of link, relates to specifically a kind of bearing pin.
Background technique
Along with improving constantly of tactics type cross-country military vehicle driver highest speed of new generation, the continuous improvement of acceleration performance, require vehicle chassis to possess higher driving safety and handling, low height independent suspension system has met the requirement of chassis design, this suspension form is that elastic element is arranged on lower cross arm, greatly reduces vehicle height of center of mass.But elastic element relies on bearing pin to be connected with lower cross arm, the pin-and-hole on transverse arm is blind hole, therefore the difficult point that is connected to become design of elastic element and lower cross arm.Adopt common bearing pin to connect, in wheel hop and rotation process, bearing pin may be deviate from and large rotation angle, and the wearing and tearing between bearing pin and elastic element are very large, cause system unreliable.
Model utility content
The purpose of this utility model is to provide a kind of locking rotation inhibiting pin shaft device, it can guarantee can not deviate from and large rotation angle in wheel hop and rotation process under the prerequisite effectively connecting, greatly reduce the wearing and tearing between bearing pin and elastic element, improved the reliability of system.
To achieve these goals, technical solution of the present utility model is: a kind of locking rotation inhibiting pin shaft device, comprises bearing pin, outside described bearing pin, one end is provided with block groove, block groove is positioned at the cross section of bearing pin, in block groove, is provided with block, and block is provided with attachment hole.
The locking rotation inhibiting pin shaft device of the utility model, wherein, described bearing pin outer end is provided with the tapped hole extending along bearing pin length direction.
The locking rotation inhibiting pin shaft device of the utility model, wherein, the bottom land of described block groove is provided with round-corner transition.
Adopt after such scheme, because one end outside the bearing pin of the locking rotation inhibiting pin shaft device of the utility model is provided with block groove, in block groove, be provided with block, block is provided with attachment hole, bolt is set in attachment hole can be fixed block and lower cross arm, guarantees that bearing pin can not be deviate from wheel hop and rotation process, the rotation that bearing pin can not produce wide-angle simultaneously, reduce the wearing and tearing between elastic element and bearing pin, make system more reliable.
Bearing pin outer end is provided with the tapped hole extending along bearing pin length direction, is convenient to the detachable maintaining of bearing pin, and the bottom land of block groove is provided with round-corner transition, avoids stress to concentrate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the locking rotation inhibiting pin shaft device of the utility model;
Fig. 2 is the sectional view that the locking rotation inhibiting pin shaft device of the utility model is connected with transverse arm.
Embodiment
As shown in Figure 1, 2, the locking rotation inhibiting pin shaft device of the utility model comprises bearing pin 11, bearing pin 11 one end, outside are provided with block groove 111, and block groove 111 is positioned at the cross section of bearing pin 11, and block groove 111 bottom lands are designed with round-corner transition, in block groove 111, be provided with block 13, block 13 is provided with attachment hole, and bearing pin 11 outer ends are also provided with the tapped hole 113 extending along bearing pin 11 length directions, and tapped hole 113 is auxiliary hole, be used for dismantling bearing pin, be convenient to change and maintenance.
When use, bearing pin 11 is inserted through elastic element in the blind hole 211 of lower cross arm 21, bolt 131 and compression spring are set in the attachment hole on block 13, block 13 is connected with lower cross arm, prevent that bearing pin 11 from deviating from or occurring the rotation of wide-angle from the blind hole of lower cross arm.
The above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in related domain make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
