Problems solved by technology

Not only are these violent abutments weakening the teeth and fingers of the park gear - causing them to be destroyed in a short time, but these vibration phenomena are also transmitted through the transmission system, thereby weakening the transmission system as well, and causing the vehicle to move back and forth

Embodiment Construction

[0024] exist Figures 1 to 5 In FIG. 2 , a gear 10 showing only two teeth 12 , 14 is mounted coaxially on an output shaft 16 of an engine of a motor vehicle, for example an electric motor of the synchronous type, the rotor of which forms the output shaft 16 .

[0025] The first and second fingers 18, 20 are mounted rotatably about the same main shaft 22 on the frame of the engine. The end of the first finger 18 has substantially the same shape and diameter as the space between the teeth 12, 14 of the gear 10, so as to engage in this space substantially without circumferential play, the end of the finger 18 The sides 24, 26 of the tooth 12, 14 are then in contact with the sides 28, 30 of the teeth (see Figure 5 ).

[0026] The ends of the second fingers 20 have for this part significantly smaller dimensions than the spaces between the teeth 12, 14 in order to be able to engage in said spaces when the vehicle is traveling at a speed of about 5 km / h.

[0027] The first finger ...

Abstract

The invention relates to a system for blocking the output shaft (16) of the engine of an automobile, of the type that comprises a toothed wheel (10) coaxially mounted on said shaft (16), and a first finger (18) mobile between a shaft (16) releasing position and a shaft blocking position in which said first finger (18) is engaged in a gap formed between two teeth (12, 14) of the wheel. According to the invention, the system includes an alignment means (20) capable of aligning a gap between two teeth (12, 14) of the wheel (10) and the first mobile finger, and the first mobile finger (18) is adapted so as to be inserted into said gap without any substantial circumferential clearance.

Description

technical field [0001] The present invention relates to the field of motor vehicles and, more specifically, to the immobilization (stationary, immobilization) of the vehicle by locking the output shaft of the engine fitted to the vehicle. Background technique [0002] The locking of the output shaft of the thermal engine of a motor vehicle is commonly used in automatic transmissions for immobilizing the vehicle. To do this, the driver engages the automatic transmission in what is known as the "parking brake". A finger is then engaged between two teeth of a gear called "park gear" mounted coaxially on the output shaft to fix the output shaft. [0003] For safety reasons, such engagement of the fingers must be possible while the vehicle is traveling at non-zero speeds close to 5 km / h. In order to make this engagement possible at non-zero speeds, the width of the fingers is substantially smaller than the spacing between two teeth of the park gear. Thus, when the finger is en...
