Abstract
The utility model provides the connection structure on dress and chassis on a kind of commercial vehicle/comm..vehicle, comprise upper junction plate and lower connecting plate, upper junction plate is fixedly connected with the subframe of commercial vehicle/comm..vehicle, the bottom of lower connecting plate is connected with the chassis member of commercial vehicle/comm..vehicle, upper junction plate and lower connecting plate offer two connecting bores respectively, two elastic cylindrical pins are installed in described two connecting bores of upper junction plate and lower connecting plate respectively, also comprise the second bolt, for upper junction plate is connected with lower connecting plate, the upper end of chassis member is extended on the top of lower connecting plate, and extension elongation is 1/2 of subframe height.This structure ensure that all tie bolts are not subject to shearing action under various operating mode, improves the safety of car load.
Description
Technical field
The utility model relates to load connection device on a kind of commercial vehicle/comm..vehicle, is applicable to the connection structure field on dress and chassis on commercial vehicle/comm..vehicle.
Background technology
When current commercial vehicle/comm..vehicle upper unit (namely upper dress) is connected with chassis, usually adopt the structure of connecting panel+U-bolt, also having the structure of employing connection bracket, there is certain deficiency in above connection mode, mainly contain following some:
1., when major-minor bicycle frame exists not along the relative motion of tie bolt axis direction, tie bolt can be subject to the effect of shearing, tie bolt may be made like this to rupture, cause great safety misadventure.
2.U type bolt tightening moment deficiency can cause the reduction of connection reliability, and moment is excessive likely damages chassis member again.
3. between connecting panel and U-bolt, there is a best spacing distance, due to the impact of the structure on chassis, this distance cannot ensure usually.
Utility model content
The utility model, for above problem, provides the connection structure on a kind of novel upper dress and chassis, can effectively overcome the above problems.
On commercial vehicle/comm..vehicle of the present utility model, load connection device comprises upper junction plate 3 and lower connecting plate 8, upper junction plate 3 is fixedly connected with the subframe 1 of commercial vehicle/comm..vehicle, the bottom of lower connecting plate 8 is connected with the chassis member 2 of commercial vehicle/comm..vehicle by the first bolt, upper junction plate 3 and lower connecting plate 8 offer two connecting bores respectively, two elastic cylindrical pins are installed in described two connecting bores of upper junction plate 3 and lower connecting plate 8 respectively, also comprise the second bolt, for upper junction plate 3 is connected with lower connecting plate 8, the upper end of chassis member 2 is extended on the top of lower connecting plate 8, and extension elongation is 1/2 of subframe 1 height.
Preferably, the first bolt is 3, lays respectively at one and falls three vertex position places of equicrural triangle.
Because tie bolt does not bear shearing, thoroughly solve bolt by the hidden danger of cutting off; The function of connecting panel and U-bolt due to adopted textural association, therefore whole connection can not re-use U-bolt, avoid the damage to chassis member, also solves the problem that both best spacing distances cannot ensure.
Accompanying drawing explanation
Fig. 1 is the front elevation of the utility model connecting device structure.
Fig. 2 is the lateral plan of the utility model connecting device structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, load connection device on commercial vehicle/comm..vehicle of the present utility model is described further.
Illustrated by attached Fig. 1 and 2, on commercial vehicle/comm..vehicle of the present utility model, load connection device comprises upper junction plate 3 and lower connecting plate 8, upper junction plate 3 is fixedly connected with the subframe 1 of commercial vehicle/comm..vehicle, selectively for welding manner connects, the bottom of lower connecting plate 8 is connected with the chassis member 2 of commercial vehicle/comm..vehicle by the first bolt, upper junction plate 3 and lower connecting plate 8 offer two connecting bores respectively, two elastic cylindrical pins are installed in described two connecting bores of upper junction plate 3 and lower connecting plate 8 respectively, also comprise the second bolt, for upper junction plate 3 is connected with lower connecting plate 8, the upper end of chassis member 2 is extended on the top of lower connecting plate 8, and extension elongation is 1/2 of subframe 1 height.
Preferably, the first bolt is 3, lays respectively at one and falls three vertex position places of equicrural triangle.
Due to the top of lower connecting plate stretch to subframe height 1/2 near, therefore, it is possible to the motion in the Y direction of restriction subframe, the application force that subframe produces in the Y direction by bottom three bolts and be installed on, two elastic cylindrical pin shareds of lower connecting plate inside, in addition, elastic cylindrical pin also limit the motion of subframe in X-direction, bear the shearing that X-direction produces, therefore, in connection, the second bolt of lower connecting plate no longer bears shearing, the application force that subframe produces in Z-direction is born by the first bolt superposed on lower connecting plate, the first bolt being positioned at bottom no longer bears shearing.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering staff in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
Claims (2)
1. load connection device on a commercial vehicle/comm..vehicle, it is characterized in that, comprise upper junction plate and lower connecting plate, upper junction plate is fixedly connected with the subframe of commercial vehicle/comm..vehicle, the bottom of lower connecting plate is connected with the chassis member of commercial vehicle/comm..vehicle by the first bolt, upper junction plate and lower connecting plate offer two connecting bores respectively, two elastic cylindrical pins are installed in described two connecting bores of upper junction plate and lower connecting plate respectively, also comprise the second bolt, for upper junction plate is connected with lower connecting plate, the upper end of chassis member is extended on the top of lower connecting plate, and extension elongation is 1/2 of subframe height.
2. load connection device on commercial vehicle/comm..vehicle according to claim 1, is characterized in that, the first bolt is 3, lays respectively at one and falls three vertex position places of equicrural triangle.
