Abstract

PURPOSE: To prevent noise and to avoid pulsating fluctuation of a motor shaft in radial direction in skid control or traction control by accepting a shaft journal in a bearing with a prescribed gap (allowance), and supporting the journal through a resilient member. CONSTITUTION: A motor shaft 1 forms a shoulder 9 against a coil of the motor, a coil spring 10 being supported by the shoulder 9 at one end and the bearing 3 or the inner race 7 of the bearing at the other end, the shaft journal 2 being supported by the inner surface 12 of the inner race 7 through an O-ring 11 within the bearing 3, the O-ring is fitted in the annular groove 13 of the shaft journal 2. The shaft journal has a gap (allowance) Δs against the bearing inner race 7 or the inner surface 12 of the bearing inner race, the play being compensated by the compressed O-ring. Thus, a fixed propagation sound can be reduced in skid control and traction control, and the O-ring can attenuate lateral force acting on the motor shaft.

For example, motors of this type are used in skid or traction control systems for vehicle braking systems. This motor is a DC motor and the rotor rotates in the stator. Such motors are used in particular for operating pumps.
With these pumps, for example, brake fluid is returned from the wheel brake cylinders to the reservoir tank.

により生ぜしめられる。There is usually "metal-to-metal support" between the motor shaft and the bearing, and the corresponding shaft journal is, for example, inserted in the bearing inner race. In this case, unacceptable noise is generated when the motor shaft rotates, and this noise is transmitted to the passenger compartment. Such noise generation occurs especially when the motor shaft is inherently loaded by skid control or traction control, in particular by pulsating fluctuations of the radial force.

As a result, it is an object of the present invention to provide a motor in which generation of inconvenient noise is prevented.

The elastic bearing of the motor shaft in the inner race of the ball bearing avoids the generation of solid propagating sound. Further, for this reason, the emission of solid-borne sound is also reduced. As a result, the actuation of this motor, for example in the brake system, is no longer felt inside the passenger compartment.

するのが望ましい。According to another aspect of the invention, the O-ring is adapted to be appropriately compressed. Therefore, the O-ring is compressed when the shaft journal is inserted into the bearing,
This limits the elasticity of the O-ring. By the way, this compression is a measure for the damping force. This compression occurs by choosing different dimensions for the O-ring outer diameter relative to the bearing inner diameter. The outer diameter of the O-ring is larger than the inner diameter of the bearing. To insert such a relatively large O-ring into a "relatively small" bearing, the O
It can only be done by compressing the ring. According to an advantageous configuration of the invention, this compression ratio is 20
% To 30% is desirable. That is, it is desirable that the O-ring be reduced by about 20% to 30% from all sides.

る。By arranging such a motor shaft elastically in the bearing in the radial direction, a significant reduction of solid-borne sound emission of the entire skid control / traction control hydraulic unit can be obtained. In particular, the O-ring damps lateral forces acting on the motor shaft, for example lateral forces originating from the pump piston in contact with the eccentric.

内に設けられている。For example, in skid control systems and traction control systems, the pump piston is operated via a DC motor. One of the main components of this DC motor is the illustrated motor shaft 1. The motor shaft penetrates the corresponding coil, and the shaft journal 2 of the motor shaft projects into and engages with the bearing 3 on both sides. In the illustrated embodiment, the bearing 3 of this type has a work molding portion 4 of the motor cover 5.
It is provided inside.

の著しい減少が得られる。The bearing journal 2 itself has a play Δ s towards the bearing inner race 7 or the inner surface 12 of the bearing inner race. This play is compensated by the compressed O-ring. In this case, compression has the following meaning. That is, the O-ring 11 has an annular groove 13 before insertion or assembly of the shaft journal 2 into the bearing 3.
It never has intimate contact with, and has a certain excess dimension in the radial direction such that the outer diameter of the O-ring is simply larger than the inner diameter d of the bearing. During assembly, this oversize is compensated by "compression". In this case, the compression ratio is about 20% to 30%. This results in a significant reduction of solid-borne sound emissions.
