Description

Балансирные подвески колес с применением спиральных пружин, работающих на закручивание, уже известны. .Balancing wheel suspension with the use of spiral springs, working on the twisting, are already known. .

Предлагаема балансирна рессорна подвеска в отличие от известных подвесок снабжена спиральной пружиной, работающей на закручивание и св занной внутренним концом с цапфой, укрепленной на балансире вдоль оси качани последнего , а внешним - с корпусом подвески. Дл удобства монтажа и демонтажа св зь внутреннего конца пружины с цапфой осуществлена посредством жестко скрепленной с пружиной втулки, надетой на цапфу и сопр женной с последней посредством шлицевого соединени , а св зь внешнего конца пружины с корпусом выполнена посредством пальца, вставленного в проушины пружины и в расточку корпуса, расположенного параллельно оси качани балансира.In contrast to the known suspensions, the proposed spring balancer suspension is equipped with a helical spring, which is operated for twisting and is connected to the axle, which is mounted on the balancer along the swing axis of the latter, and the outer end to the suspension body. For ease of mounting and dismounting, the inner end of the spring is connected to the trunnion by means of a sleeve rigidly fastened to the spring, worn on the trunnion and joined to the latter by means of a splined connection, and the outer end of the spring is connected to the casing by means of a finger the bore of the body located parallel to the axis of swing of the balancer.

С целью обеспечени работы лальца на многократный срез, внеш1ИЙ конец пружины выполнен в виде :оставленной из р да проущин гребенки , зубь которой вход т в пазы,, сделанные в теле корпуса подвески.In order to ensure the operation of the lalez on a multiple cut, the outer end of the spring is made in the form of: left of a series of comb holes, the tooth of which fits into the grooves, made in the body of the suspension body.

На фиг. 1 изображен общий вид балаксирной подвески, а на фиг. 2 - разрез балансирной подвески по АОБ фиг. 1.FIG. 1 shows a general view of a balaxier suspension, and FIG. 2 shows a section of a balancing suspension according to the AOB of FIG. one.

К боргу 10 корпуса машины около его днища // крепитс корпус 5 подвески (фиг. 2), на который насажен балансир 3. Корпус 5 служит осью качани балансира и опорой наружного конца пружины. Внутри корпуса 5 помещаетс спира. пружина /, изготовленна из полосовой стали. Наружный конец пружины / имеет вид гребенки, составленной из р да проушин, который пальцем 7 крепитс к корпусу 5. К внутреннему концу пружины f приварена шлицованна втулка 2, насаженна на шлицы цапфы }2 на крышке 4 балансира 3. Две щпильки 9 св зывают балансир 3 с крышкой 4 и посредством последней с пружиной /, котора воспринимает скручивающий момент. Упорна планка 8 предохран ет балансир 3 от осевого смещени на корпусе 5. Крышка 6 корпуса 5 упро469To the Borg 10 of the car body near its bottom // the body 5 of the suspension (Fig. 2) is attached, on which the balance weight 3 is mounted. The body 5 serves as an axis for swinging the balance weight and supporting the outer end of the spring. A spiral is placed inside the housing 5. spring / made of strip steel. The outer end of the spring / has the shape of a comb composed of a series of lugs, which is fastened with a finger 7 to the housing 5. A slotted sleeve 2, mounted on the splines} 2 on the cover 4 of the balance bar 3 is welded to the inner end of the spring f. Two studs 9 connect the balancer 3 with a cover 4 and by means of the latter with a spring /, which perceives the twisting moment. The stop bar 8 prevents the balancer 3 from axial displacement on the housing 5. The cover 6 of the housing 5 is prevented

Claims

1. Balanced spring flow for the support wheels of tracked and wheeled machines, equipped with a coil spring, which works for twisting and is connected to the inner end of the axle, mounted on the balancer along the swing axis of the latter, and the outer end with the suspension body, which is convenient for mounting and dismounting the inner end of the spring

by means of rigidly fastened: With a spring bushing, worn on the trunnion and connected to the latter through a slit joint, and the connection of the outer end of the spring to the casing is made with a finger inserted into the spring lugs and into the bore of the casing located parallel to the balance axis of the balancer.

2. The shape of the suspension according to claim I, characterized in that in order to ensure that the finger works on a multiple cut, the outer end of the spring is made in the form of a comb composed of a number of lugs, the tooth of which fits into the grooves made in the body of the suspension body.
