Embodiment Construction

[0011] The invention provides an automatic power transmission. On the two shafts of the transmission to realize speed change, at least one high-speed gear and at least one low-speed gear with different diameters and numbers of teeth are fixed at intervals on one shaft, and the other shaft is splined on the other shaft. There are at least two modified wedge-type one-way devices without inner rings side by side, and the inner rings of each one-way device are integral sliding sleeves with protrusions in the middle that can slide laterally along the splines ; At least one high and low speed gear and at least one low speed gear with different diameters and numbers of teeth are provided on the outer rings of the separate one-way devices.

[0012] Preferably, when the sliding sleeve slides axially along the spline shaft, it stops at a certain position according to the control requirements. At this time, the protrusion on the sliding sleeve can correspond to a specific one-way device, ...

Abstract

The invention relates to an automatic power speed changer and belongs to the field of mechanical power transmission. According to the automatic power speed changer, on two shafts, achieving speed changing, of the speed changer, at least one high-speed gear and at least one low-speed gear which are provided with different diameters and different numbers of teeth are fixed on one shaft at intervals, at least two remodeled non-inner-ring wedged-block type isolators are axially and detachably sleeved on a spline of the other speed changing shaft in parallel, an inner ring of each isolator is an overall slide sleeve which is provided with a protrusion in the middle and can horizontally slide along the spline, and at least one high-low speed gear and at least one low-speed gear which have different diameters and different numbers of teeth are arranged on an outer ring of each detachable isolator. The automatic power speed changer can reduce self weight and cost and facilitate achieving speed changing.

Description

technical field [0001] The invention belongs to the field of mechanical power transmission. Background technique [0002] At present, in order to achieve high and low gear shifting in mechanical facilities, usually in order to solve the problem of convenient meshing of high and low gears, additional devices such as synchronizers are used. interruption. Especially for the novice drivers of manual transmission cars and electric cars, which are already hundreds of millions in our country, not only the power interruption caused by shifting gears seriously affects the speed of the vehicle and the smoothness of the road, but also because of the complex structure of the transmission, it is a problem for cars, especially electric cars. The cost of a major vehicle system of a vehicle will account for a large part of the vehicle, greatly increasing the weight and price of the vehicle, and affecting the development of the transportation and electric vehicle industries.
