Embodiment Construction

[0014] Embodiments of the present invention will be described below with reference to the drawings. As shown in Figure 1 and Figure 2, a free synchronous self-locking braking reverse gear is characterized in that a lock pin type inertia synchronizer and a power center gear 13 are positioned on the spline shaft on the power shaft 2, and used Snap rings hold them in place. Lock pin type inertial synchronizer is made up of gear holder 3, adapter sleeve 6, lock pin 1, positioning pin 5, friction cone ring 4, friction cone disc 7 and positioning snap ring. The adapter sleeve 6 is in sliding connection with the gear seat 3 , and the locking pins 1 and positioning pins 5 are evenly distributed in pairs on the adapter sleeve 6 . The two ends of the locking pin 1 are respectively fixed on the friction cone ring 4, the positioning pin 5 is positioned in the middle of the hole of the adapter sleeve 6 with a pin, and its two ends are inserted in the groove on the friction cone ring 4. T...

Abstract

In the invention, on the power shaft are disposed a synchronizer and a power central gear, and between them is sleeved a planet gear shaft brake disc in a certain position. On the brake disc are disposed an engagement tooth, a friction conical disc, a brake, a planet gear shaft and a planet gear separately. The planet gear and the power central gear are engaged via an internal gear ring. The planet gear shaft brake disc is braked via the brake to realize the reverse of the passive shaft, so as to achieve the goal of the reverse running.

Description

1. Technical field [0001] The invention relates to a reverse gear device for a motor vehicle, in particular to a free synchronous self-locking braking reverse gear. 2. Background technology [0002] On various motor vehicles at present, most of their reverse gears are integrated with the transmission mechanism, and the speed change mechanism and the reverse gear mechanism of the motor vehicle have idling, mechanical wear and loss of mechanical energy when the motor vehicle is advancing, which shortens the service life of the transmission. The speed change and the reverse gear mechanism of speed changer can not become one with power shaft and do synchronous rotation during forward running, can not directly switch to become reverse gear and reverse gear travel. Moreover, the volume is large, the mechanical structure is not compact, and the manufacturing cost is relatively high, so it cannot be used in conjunction with a certain fully automatic continuously variable transmissio...
