Abstract
A kind of back axle bottom plate, relates to a kind of automobile axle accessory, and including panel seat, the support that is integrally connected to panel seat two ends, the center of panel seat is provided with hole, location, and this panel seat is set to L-type groove structure for the corner installing U-bolt；Described panel seat is designed with lightening recesses at the binding face with axle housing.Owing to bolt hole is changed to reach the L-type groove structure of U-bolt positioning action by this utility model, it is cross for making whole panel seat face, alleviates panel seat weight.But also the binding face of panel seat Yu axle housing is designed with lightening recesses, in the case of meeting intensity and laminating width, also reduce further the weight of back axle bottom plate.This utility model may be cast as molding owing to eliminating or is cut directly into type at the operation of auger shell keyhole, and the cross state of panel seat, reduce cost of labor and processing cost.
Description
Technical field
This utility model relates to a kind of automobile axle accessory, particularly a kind of back axle bottom plate.
Background technology
Along with the expansion of China's automobile market, the requirement to auto parts and components is more and more higher, existing automobile axle, its
Bottom plate is conventionally used to install the structure of 4 U-bolts and is typically designed as bolt hole structure (see figure 1), the weight of this type of panel seat
Amount is big, and Drilling operation is more difficult, considerably increases material cost and processing cost.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of back axle bottom plate, to solve what prior art existed
Weight is big, Drilling operation is more difficult, increase the weak point of cost.
The technical scheme solving above-mentioned technical problem is: a kind of back axle bottom plate, including panel seat, is integrally connected to panel seat two
The support of end, the center of panel seat is provided with hole, location, and this panel seat is set to L-type groove structure for the corner installing U-bolt.
Further technical scheme of the present utility model is: described panel seat is to be designed with loss of weight recessed with the binding face of axle housing
Groove.
Further technical scheme of the present utility model is: the end face of described L-type groove structure and the gap A1 of U-bolt,
A2 is 0～2mm, and the fillet R that dodges of L-type groove structure is 2～8 mm.
Further technical scheme of the present utility model is: be additionally provided with reinforcement between described panel seat and support.
Owing to using said structure, the back axle bottom plate of this utility model compared with prior art, has following useful effect
Really:
1. alleviate pts wt
Owing to bolt hole is changed to reach the L-type groove structure of U-bolt positioning action by this utility model, make whole plate
Seat surface is cross, significantly reduces panel seat weight.Subtract additionally, the binding face of panel seat with axle housing is also designed with by this utility model
Weight groove, also reduce further the weight of back axle bottom plate in the case of meeting intensity and laminating width.
2. handling ease, reduces cost:
Owing to bolt hole is changed to reach the L-type groove structure of U-bolt positioning action by this utility model, eliminate brill
May be cast as molding at the operation of hole machined, and the cross state of panel seat or be cut directly into type, greatly reducing artificial one-tenth
Basis and processing cost.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic of the back axle bottom plate of this utility model is made further
Bright.

Detailed description of the invention
Embodiment one
A kind of back axle bottom plate 3, including panel seat 31, the support 32 that is integrally connected to panel seat 31 two ends, the center of panel seat 31
Being provided with hole 311, location, this panel seat is set to L-type groove structure 312, the end of L-type groove structure for the corner installing U-bolt 2
Face and gap A1=1mm, the A2=1mm of U-bolt, the fillet R that dodges of L-type groove structure is 5 mm.
Described panel seat is also designed with lightening recesses 313 at the binding face with axle housing, also sets between panel seat 31 and support 32
There is multiple reinforcement 33.
During use, first back axle bottom plate 3 is seated against plate 4 by lower plate and be arranged on lower suspension beam 5, then by rear axle housing assembly
Axle housing in 1 is arranged on the panel seat 31 of back axle bottom plate 3, and with U-bolt 2, axle housing, lower plate is seated against plate 4, lower suspension beam 5
Link together.
As a kind of conversion of the present embodiment one, the end face of described L-type groove structure and gap A1, A2 of U-bolt
Numerical value can increase or reduce, typically take 0～2mm, equally, the value dodging fillet R of L-type groove structure is generally 2～8
mm。
