Description

Велосипедные трехскоростные коробки перемены передач с посто нным зацеплением шестерен и переключением передач посредством скольз щей шпонки, известны.Bicycle three-speed gearboxes with permanent gearing and gear shifting by means of a sliding key are known.

В известных трансмисси х от двигател  к ведуш,ему колесу велосипеда недостатком  вл етс  мала  эффективность использовани  мошности двигател , завис ша  от условий движени , а также сложность самой трансмиссии. Эти недостатки устранены применением приставной коробки перемены передач к велосипедному двигателю, котора  выполнена с первичным валом, жестко св занным с валом двигател .In the known transmissions from the engine to the vedush, the wheel of a bicycle lacks the efficiency of using engine power, depends on driving conditions, as well as the complexity of the transmission itself. These drawbacks are eliminated by applying an add-on gearbox to the bicycle engine, which is made with the primary shaft rigidly connected to the engine shaft.

На чертеже изображена схема коробки перемены передач.The drawing shows a diagram of the gearbox.

Велосипедна  трехскоростна  коробка перемены передач выполнена с посто нным зацеплением шестерен и переключением передачи посредством скольз щей щнонки. На ведущем валу /, св занном с валом двигател , жестко насажена шестерн  2, вход ща  в посто нное зацепление с щестерней 3 промежуточного вала 4, вдоль которого перемещаетс  шпонка 5 (кулачок), осуществл юща  св зь с валом 4 шестерен 6, 7 и 8, свободно по нем врашающихс .The bicycle three-speed gearbox is made with permanent gearing of gears and gear shifting by means of a sliding puck. A gear 2 is rigidly mounted on the drive shaft I connected to the engine shaft, engaging in constant engagement with the bristles 3 of the intermediate shaft 4, along which the key 5 (cam) moves, communicating with the shaft 4 of the gears 6, 7 and 8, freely matched by him.

Шестерни 7 и S промежуточного вала 4 вход т в посто нное зацепление с шестерн ми 9 к 10 ведомого вала 11, на котором последние закреплены жестко. Шестерн  12 включена посредством паразитной шестерни /5 заднего хода, закрепленной на валу 14, смонтированной в картере 15 мотора, на шестерню 6 промежуточного вала 4.The gears 7 and S of the intermediate shaft 4 are permanently engaged with the gears 9 and 10 of the driven shaft 11, on which the latter are rigidly fixed. Gear 12 is enabled by parasitic gear / 5 reverse, mounted on the shaft 14 mounted in the crankcase 15 of the motor, on the gear 6 of the intermediate shaft 4.

Переключение передач производ т перемещением вдоль промежуточного вала 4 щпонки 5, осуществл емым посредством зубчатой рейки 16.The gear shift is made by moving along the intermediate shaft 4 the pins 5, carried out by means of the toothed rack 16.

Нре-дмет изобретени Hre-dmet invention

Велосипедна  трехскоростна  коробка перемены передач с посто нным зацеплением шестерен и переключением передач посредством скольз щей шпонки, отличаюша с  тем, что, с целью упрощени  конструкции трансмиссии велосипеда, она выполнена с первичным валом, жестко св занным с валом двигател .A bicycle three-speed gearbox with constant gear engagement and gear shifting by means of a sliding key is different in that, in order to simplify the design of the bicycle transmission, it is made with a primary shaft rigidly connected to the engine shaft.
