Description

Rear-suspending bearing

Technical field

The utility model relates to auto parts fields, more specifically, it relates to which rear-suspending supports.

Background technique

As engine and speed changer quality are continuously increased, engine torque and power constantly increase, 80 years 20th century Rubber bearing has been not suitable with current needs after the steyr engine mounting that generation introduces, and often occurs connection bolt looseness too early And fracture influences user's normal use so that exhaust pipe etc. can be caused to damage.

Utility model content

The utility model overcomes the deficiencies in the prior art, provide a kind of cost savings, structure it is simple and safe after Suspension bearing.

The technical solution of the utility model is as follows:

Rear-suspending bearing, including positioning sleeve, shell, inner core and rubber parts, positioning sleeve are embedded in four mounting holes of shell On, rubber parts vulcanizes bonding, shell injection molding adhesion with inner core respectively；Shell is integrally in annulus cylindricality, and four of lower part of the housing Mounting hole connecting vehicle frame, inlay location set in shell through hole, whole positioning sleeve is also in annulus cylindricality, and outside, which is uniformly distributed, to be set Annular groove, setting annular convex platform corresponding with annular groove on through hole are set, the upper outside of shell is uniformly distributed setting rectangular channel； Inner core is integrally in cross, and is symmetrical arranged the shape hole for needing to connect, and rubber parts wraps up inner core.

Further, the length of rectangular channel is 2cm, width 0.8cm, with a thickness of 0.3cm.

Further, rubber parts extension is more than 1/3 but the area less than 1/2 and shell bond.

Further, rubber parts and inner core are integrally formed by insert injection moulding.

Advantage is the utility model compared with prior art: the design of the utility model structure is simple, reasonable, easy to make, Practical, production cost is relatively low, easily promotes the use of.The utility model overall structure mitigates pts wt, reduction group Process is filled, part manufacturing cost is reduced, improves part production efficiency.

Detailed description of the invention

Fig. 1 is the structure chart of the utility model；

Fig. 2 is another angled arrangement figure of the utility model；

Fig. 3 is that the shell of the utility model removes the structure chart of a positioning sleeve；

Fig. 4 is the face upwarding assumption diagram of the utility model.

It is identified in figure: positioning sleeve 1, shell 2, inner core 3 and rubber parts 4.

Specific embodiment

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 1 to 4, rear-suspending supports, including positioning sleeve 1, shell 2, inner core 3 and rubber parts 4, and positioning sleeve 1 is inlayed On four mounting holes of shell 2, rubber parts 4 is arranged between shell 2 and inner core 3.Whole shell 2 is in annulus cylindricality, and The mounting hole connecting vehicle frame of lower part four of shell 2, inlay location set 1 in shell through hole, whole positioning sleeve 1 is also in annulus column Shape, outside are uniformly distributed setting annular groove, setting annular convex platform corresponding with annular groove on through hole, by pairing setting with Reinforce the stability of connection.The upper outside of shell 2 is uniformly distributed setting rectangular channel, this rectangular channel has the work of reinforcement structure With promotion deformation resistance.The length of specific rectangular channel is 2cm, width 0.8cm, with a thickness of 0.3cm.Wherein shell 2 is whole Plastics are used, and positioning sleeve 1 uses the aluminium squeezed out using steel, inner core 3, reaches firm place's metallic steel aluminum material, can save Place uses high rigidity plastics.Inner core 3 and rubber parts 4 are all firstly vulcanized, then are integrally formed with insert injection moulding, and substantially reduce part weight Amount reduces assembling procedure, improves part production efficiency.

Preferably, it is in cross that inner core 3 is whole, and be symmetrical arranged the shape hole for needing to connect, shape hole with need to connect The auto parts position connect is adapted, and rubber parts 4 wraps up inner core 3, and a part therein is connected and fixed with positioning sleeve 1.Rubber 4 extension of part is more than 1/3 but the area less than 1/2 and shell 2 are fixed, can be fixedly connected with and provide well bigger resist Deformation range.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art Art personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications Also it should be regarded as in scope of protection of the utility model.
