Problems solved by technology

[0002] At present, CVTs mainly adopt structures such as steel belt type and friction ring type. These structural methods all use friction transmission, resulting in relatively low torque that the existing CVTs can bear, and basically can only be applied to small cars and other loads. Occasions, the scope of use is limited, and friction transmission can easily lead to rapid temperature rise of parts, resulting in greater power loss, low transmission efficiency, and shorter service life of parts

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

[0017] Such as Figure 1 to Figure 6 As shown, a continuously variable transmission vehicle described in this embodiment includes a vehicle body and a continuously variable transmission arranged in the vehicle body.

[0018] The continuously variable transmission includes a front housing 1, a rear housing 2, a driven grooved disc 3 and a variable modulus drive device 4, the driven grooved disc 3 is arranged on the rear housing 2, and the driven grooved disc The middle part of 3 is provided with a circular blank part, and the forward groove 31 and the reverse groove 32 arranged intersectingly are arranged on the driven groove plate 3 at intervals, and the forward groove 31 and the reverse groove 32 are all formed from the edge of the circular blank part. Ext...

Abstract

The invention discloses a continuously variable transmission automobile which comprises a front shell, a back shell, a driven slotted disc and a variable-modulus driving device. Crossed forward slotsand reverse slots are formed in the driven slotted disc in a spaced mode, the variable-modulus driving device comprises a conical input shaft, a reducing driving motor, a reducing screw, a reducing nut and a plurality of sliding jaws, the taper of the input shaft is equal to the included angle formed between two adjacent forward slots or two adjacent reverse slots, a dovetail slot is formed in theinput shaft, the reducing nut is provided with pusher dogs, the sliding jaws are embedded into the dovetail slot, and the other ends of the pusher dogs are sleeved with one ends of the sliding jaws;by arranging the reducing screw, the reducing nut and the pusher dogs, the sliding jaws are driven to slide along the surface of the conical end of the input shaft, and therefore the modulus of the input shaft is changed, and the number of the sliding jaws meshed with the forward slots and reverse slots in the driven slotted disc is changed. Then, the rotating speed of the output shaft is changed,continuously variable transmission is achieved, temperature rise is small, power loss is small, the transmission efficiency is high, and the service life of all the parts is longer.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a continuously variable speed automobile. Background technique [0002] At present, CVTs mainly adopt structures such as steel belt type and friction ring type. These structural methods all use friction transmission, resulting in relatively low torque that the existing CVTs can bear, and basically can only be applied to small cars and other loads. Occasions, the scope of use is limited, and friction transmission can easily lead to rapid temperature rise of parts, resulting in greater power loss, low transmission efficiency, and shorter service life of parts. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcoming and provide a continuously variable speed vehicle. [0004] In order to achieve the above object, the specific solution of the present invention is as follows: A continuously variable transmission vehic...
