Abstract
The utility model provides a multi-functional skeleton oil blanket is formed by skeleton oil blanket and slide bearing assembly. Wherein, the design of skeleton oil blanket has the draw-in groove, and slide bearing design has the boss, and slide bearing's boss can imbed the draw-in groove of skeleton oil blanket for skeleton oil blanket and slide bearing become a subassembly. The utility model discloses cancelled skeleton oil blanket and slide bearing along the structure that the axial distributes in proper order, and with slide bearing embedding skeleton oil blanket, assemble an subassembly with both, can realize simultaneously sealed and support the effect of axis body. The structure can reduce the axial dimension from the width of two parts to the width of one part, and provides more possibilities for the overall arrangement of the whole vehicle.
Description
Technical Field
The utility model belongs to the steering system field especially relates to a multi-functional skeleton oil blanket.
Background
The steering gear is an important component of the automobile, and the installation space provided for the steering gear in the whole automobile arrangement process is limited, so that how to minimize the volume of the steering gear on the basis of ensuring the product performance is a problem which must be considered in the design process of the steering gear.
In the upper end portion of the input shaft of the steering gear housing, a sliding bearing is generally disposed to function as a support shaft body, and in addition, a skeleton oil seal is disposed to function as a seal, both of which are axially distributed. For the whole vehicle, sometimes, in order to conveniently arrange a transmission shaft and reduce the moment fluctuation in the working process of a universal transmission shaft, the axial size of an input shaft of a steering gear is required to be as short as possible; the sequential axial distribution of the framework oil seal and the sliding bearing is mutually contradictory to the requirement.
Disclosure of Invention
For solving the deficiencies of the prior art, the utility model provides a multifunctional framework oil seal.
The utility model adopts the following technical scheme: the multifunctional framework oil seal is formed by assembling a framework oil seal and a sliding bearing, wherein the framework oil seal is provided with a clamping groove, the sliding bearing is provided with a boss, and the boss of the sliding bearing can be embedded into the clamping groove of the framework oil seal, so that the framework oil seal and the sliding bearing become an assembly.
Furthermore, a framework is arranged in the rubber sealing body of the framework oil seal.
Furthermore, a tightening spring is arranged at the lip of the framework oil seal.
Furthermore, a plurality of raised dots are arranged on the outer circle surface of the framework oil seal rubber sealing body.
Compared with the prior art, the utility model discloses cancelled skeleton oil blanket and slide bearing along the structure that the axial distributes in proper order, and with slide bearing embedding skeleton oil blanket, assemble an subassembly with both, can realize simultaneously sealed and support the effect of axis body. The structure can reduce the axial dimension from the width of two parts to the width of one part, and provides more possibilities for the overall arrangement of the whole vehicle.

Detailed Description
With reference to fig. 1, fig. 2 and fig. 3, the multifunctional skeleton oil seal (100) of the present invention is assembled by the skeleton oil seal (1) and the sliding bearing (2). Wherein, skeleton oil blanket (1) design has draw-in groove (7), and slide bearing (2) design has boss (8), and the boss (8) of slide bearing (2) can imbed draw-in groove (7) of skeleton oil blanket (1) for skeleton oil blanket (1) and slide bearing (2) become an subassembly.
A framework (5) is arranged in a rubber sealing body (3) of the framework oil seal (1), the framework (5) plays a role in reinforcement, and the framework oil seal (1) keeps shape and tension.
The lip of the framework oil seal (1) is provided with a tightening spring (4), the contraction force of the tightening spring (4) generates certain radial tension to the shaft, and meanwhile, the self-tightening force of the framework oil seal (1) can be compensated at any time.
The outer circle surface of the framework oil seal (1) and the rubber seal body (3) is provided with a plurality of raised dots (6), and the raised dots (6) can meet the requirement of assembly simplicity while ensuring the interference requirement of the multifunctional framework oil seal (100) and the shell hole.
Claims (4)
1. The utility model provides a multi-functional skeleton oil blanket for steering gear, its characterized in that: the multifunctional framework oil seal is formed by assembling a framework oil seal and a sliding bearing, wherein the framework oil seal is provided with a clamping groove, the sliding bearing is provided with a boss, and the boss of the sliding bearing can be embedded into the clamping groove of the framework oil seal, so that the framework oil seal and the sliding bearing become an assembly.
2. The multifunctional framework oil seal of claim 1, wherein: furthermore, a framework is arranged in the rubber sealing body of the framework oil seal.
3. The multifunctional framework oil seal of claim 1, wherein: and a tightening spring is arranged at the lip of the framework oil seal.
