Problems solved by technology

[0004] At present, the transmission system of energy-saving racing cars is friction belt transmission and gear transmission. The clutch method used when the engine stops rotating is a jaw clutch. However, there are some defects in the existing transmission methods. The friction belt transmission has elastic sliding and overall slippage. , the gear transmission has the defects of high installation accuracy, high cost and complicated long-distance transmission structure. The jaw clutch has a large weight and a relatively complicated structure.

Embodiment 1

[0033] Example 1: An energy-saving racing car transmission system (see attached figure 1 Attached figure 2 Attached image 3 ), including the engine 10, the driving shaft 1, the intermediate shaft 4 and the driven shaft 6 fixed on the frame 11, the driving wheel 2 is fixed on the driving shaft, and the hub tube is sleeved on the intermediate shaft 4 through the deep groove ball bearing , The hub tube is fixed with a primary driven wheel 5 and primary driving wheel 8, and a secondary driven wheel 7 is fixed on the driven shaft 6, between the driving wheel 2 and the primary driven wheel 5, the primary driving wheel 8 and the second The secondary driven wheels 7 are connected by a transmission chain 3. The transmission chain uses a single-row roller chain, the intermediate shaft is parallel to the driving shaft and the driven shaft, and the middle shaft is at the symmetrical position of the driving shaft and the driven shaft. The diameter of the primary driven wheel is greater th...

Embodiment 2

[0035] Embodiment 2: An energy-saving racing car transmission system. The difference from the embodiment is that the pawl is hinged to the drive plate, and a reset tension spring 24 is connected between the pawl and the drive plate (see attached Picture 11 ), when the engine is rotating, the centrifugal force of the pawl is greater than the elastic force of the return tension spring. Refer to Example 1 for the rest of the structure.

Embodiment 3

[0036] Example 3: An energy-saving racing car transmission system, the center of gravity of the pawl in the ratchet clutch is an eccentric structure (see attached Picture 12 ), the pawl includes a pawl head 28 and a pawl body 26, the pawl head has a triangular end 25, the end of the pawl body is provided with a reaming hole 27, the center of gravity of the pawl is biased towards the pawl head, the width of the pawl is from the head to The tail end of the claw body gradually decreases. Refer to Embodiment 1 or Embodiment 2 for the rest of the structure.

Abstract

The invention relates to a transmission system of an energy-saving competitive racing car. According to the transmission system of the energy-saving competitive racing car, a two-level chain is used for transmission, a wheel hub which drives rear wheels is arranged on a driven shaft in a sleeved mode, a ratchet wheel clutch is arranged between the driven shaft and the wheel hub and comprises a ratchet wheel, pawl and a loosening spring, the ratchet wheel is fixed to the wheel hub, the pawl connects the ratchet wheel to the driven shaft, and the loosening spring is connected with the pawl and is used for loosening the pawl and the ratchet wheel. According to the transmission system of the energy-saving competitive racing car, the pawl is meshed with or disengaged from ratchets so that clutch can be achieved, the structure is simple, and energy consumption can be reduced.

Description

Technical field [0001] The invention relates to a transmission system, in particular to an energy-saving racing car transmission system used in energy-saving competitions. Background technique [0002] At present, energy conservation and environmental protection are the trend of industrial development, as well as the end point of national scientific and technological research and automobile manufacturers' focus on research and development. The Honda Energy Conservation Competition meets the requirements of the times to improve social energy conservation and environmental protection awareness. The energy conservation competition competes with 1L fuel driving. How many kilometers of the competition, the competition is an activity focusing on energy and creating a conservation-oriented society. It is also a global energy-saving activity under the social background of air pollution caused by exhaust emissions caused by the rapid increase of vehicles. The simplicity of the economy mak...
