Description

The utility model relates to the field of transport engineering, namely to the design of a single-wing and double-wing door of passenger vehicles and the mechanism of their drive.

A device is known for automatically opening a vehicle door with a rotatable strut (USSR author's certificate SU No. 1258320 dated 12/01/1983) containing a pneumatic actuator cylinder connected to the vehicle door with a rotary arm with a strut and also through the upper and lower levers with hinges.

Known double-leaf pivoting door of a passenger vehicle (patent for PM RU No. 24152 dated 12.24.2001), containing sashes consisting of vertical struts and cross-members of the supporting frame, glazing inserted into the frame, rubber seals, lower protective screen, handrail and system leaf drive, consisting of vertical axes with supports in the upper and lower parts, mounted on the body, horizontal levers of the axes connected to the drive mechanism, the upper guide roller, the lower guide stop.

A disadvantage of the known doors and their drive mechanisms is the lack of devices for adjusting the position of the door leaf relative to the door frame and adjusting the position of the elements of the drive mechanism relative to the door leaf when changing their position relative to the frame, both during the initial installation of the door in the body doorway and during repair work.

The famous bus "Neman 520101" (https://belautoprom-g2n.jimdo.com/neman/neman-5201/neman-520101/) with a drive mechanism for each door leaf that opens inside the cabin. The leaf drive mechanism consists of a swing arm, which is supported by an adjustable ball bearing, lower and upper swing arms of the leaf, one end of each of which is mounted on the swing arm, and the other ends are pivotally connected to the upper and lower swing axes of the leaf, mounted on brackets mounted on the upper and lower crossbars of the sash.

The known door drive mechanism 40N3R63 / 116T1B028 (1B040) of the LiAZ-621371 bus (http://sinref.ru/avtomobili/Liaz/002_ _{_} Liaz_621321_4klass_rukovodstvo_2011 / 215.htm, prototype), which has one or two doors, which open. The door leaf drive mechanism consists of a pivot strut, which is supported by a ball bearing, consisting of a thrust washer, ball and screw mounted on a support mounted on the floor of the body, and the upper part of the rack is attached to the body with an arm with a sliding bearing.

The door leaf through the hinges is connected to two levers mounted on a swing arm. The rotation of the rack is carried out by the pneumatic cylinder of the door drive mechanism through the rotation lever, mounted on the splines of the upper end of the axis. The linear path of movement of the inner edge of the sash is defined by a guide roller mounted on an axis and moving in a guide mounted on the upper cross member of the door frame.

The disadvantage of this drive mechanism is the lack of regulation of the position of the door leaf relative to the frame and body.

Known ball bearing of the vehicle (patents PM RU No. 158814 dated 06/18/2015 and PM RU No. 161484 dated 04/02/2015), comprising a body in the form of a glass with an external thread and an internal spherical cavity, and a ball finger, consisting of a ball head located in ball cavity, and a shank with a threaded end, which is used for fastening in the fixed part of the vehicle body. The glass is fixed in a cage movable relative to the body.

To prevent the ingress of abrasive particles between the spherical surfaces of the glass and the ball head, a protective cover of elastomer is installed on the glass and the shank of the finger.

The ball bearing of this design is not intended for the reciprocating movement of the holder with the glass at a large angle of about 20 ° relative to the vertical axis of the ball finger, excludes the regulation of the position of the glass relative to the holder, and repair requires the replacement of the ball bearing assembly due to its inseparability.

The body of the ball joint of the vehicle is known (patents for PM RU No. 35852 dated 08.08.2003 and PM RU No. 566512 dated 04.07.2005) with an internal cavity in the form of a hemisphere turning into a cylindrical part. The housing design does not provide for the possibility of protecting the inner surface from abrasive particles during its reciprocating motion relative to the relatively motionless protective cover.

A pivoting door of a passenger vehicle body is known (application RU No. 2018120528/11 (032360) dated 06/04/2018, the decision to grant a patent for PM from 08/29/2018, prototype), containing two struts and an upper cross member containing, according to at least a door leaf, made in the form of a frame with upper and lower rigid cross-pieces of the leaf, as well as side, upper and lower seals; a rotary stand with a rotation lever fixed at its upper end, the lower part of which is mounted on a vertically adjustable lower ball bearing mounted on the floor of the body, and the upper part of the rack is mounted in a detachable sliding bearing, the housing of which is fixed by a threaded connection to the body; a pneumatic drive of a rotary rack having a horizontally movable pneumatic cylinder with a piston and a rod pivotally connected to a rack rotation lever, with a housing pivotally mounted on the body using a mounting bracket; the upper arm of the sash drive mechanism, the first end of which is rigidly mounted on a rotary stand below the split bearing, and the second end is pivotally mounted on the upper axis of rotation of the sash, mounted on the first bracket of the upper cross member of the sash; the lower lever of the sash drive mechanism, rigidly fixed to the pivot rack and pivotally on the lower axis of rotation of the sash, mounted on the lower bracket mounted on the lower cross member of the sash; a leaf guide fixed above its upper cross member; a second bracket fixed on the upper cross member of the leaf with an axis and with a roller at the end of the axis movable in the leaf guide, with a distance between the axis with the roller and the leaf plane greater than the distance between the upper axis of rotation of the leaf and the leaf plane.

The technical problem solved by the utility model is to increase the manufacturability of manufacturing a door of a passenger vehicle and reduce the complexity of adjusting the position of the door leaves relative to the frame, both during the initial installation of the door in the body doorway and during repair and adjustment work during the operation of the vehicle.

The technical problem is solved in the design of the door of a passenger vehicle, fixed in the doorway of the body, having a frame consisting of two pillars and an upper cross-section, containing at least a door leaf, made in the form of a frame with upper and lower rigid cross-pieces of the leaf, and side, top and bottom seals; a rotary stand with a rotation lever fixed at its upper end, the lower part of which is mounted on a vertically adjustable lower ball bearing mounted on the floor of the body, and the upper part of the rack is mounted in a detachable sliding bearing, the housing of which is fixed by a threaded connection to the body; a pneumatic drive of a rotary rack having a horizontally movable pneumatic cylinder with a piston and a rod pivotally connected to a rack rotation lever, with a housing pivotally mounted on the body using a mounting bracket; the upper arm of the sash drive mechanism, the first end of which is rigidly mounted on a rotary stand below the split bearing, and the second end is pivotally mounted on the upper axis of rotation of the sash, mounted on the first bracket of the upper cross member of the sash; the lower lever of the sash drive mechanism, rigidly fixed to the pivot rack and pivotally on the lower axis of rotation of the sash, mounted on the lower bracket mounted on the lower cross member of the sash; a leaf guide fixed above its upper cross member; the second bracket fixed on the upper cross-member of the leaf with an axis and with a roller on the axis end movable in the leaf guide, with a distance between the axis with the roller and the leaf plane greater than the distance between the upper axis of rotation of the leaf and the plane of the leaf, while the lower part of the swing arm has an inner thread, and an adjustable ball bearing consists of an installed cup with an external thread with a lock nut and flats for a wrench, with an internal cavity with a cylindrical surface passing into the bottom with a spherical o surface, with a spherical ball head located in the inner cavity mounted on a thrust bearing mounted on the floor of the body; a separable sliding bearing is fixed at the end of the mounting plate having grooves perpendicular to the body wall; the first and second brackets have horizontal grooves in their bases, mounted on the upper cross member of the sash using threaded connections; the hinge connecting the second end of the upper arm to the upper axis of rotation of the leaf of the leaf drive mechanism has a bearing, and the upper axis of rotation of the leaf is fixed to the first bracket by a threaded connection with the possibility of adjusting its height position; the axis with the roller is fixed in the second bracket by a threaded connection with the possibility of regulating its position relative to the guide.

To regulate the vertical position of the pneumatic actuator, the pneumatic cylinder body is attached to the mounting bracket in the form of a channel with a threaded connection with the possibility of adjusting the position in height.

To exclude spontaneous vertical movement of the sash during the movement of the bus, the position lock of the rotary stand is installed below the split bearing of the height.

To exclude spontaneous vertical movement of the sash during the movement of the bus, the position lock of the rotary stand is installed below the split bearing of the height.

To reduce sliding friction and wear rate of the ball joint between the bottom of the glass and the ball head of the finger there is an insert made of antifriction polymer material or bronze.

To prevent abrasive particles from entering the surface of the ball joint, the cup has a smooth cylindrical surface below the surface of the wrench, and a protective cover is installed on the ball finger, the upper part of which has a girdle whose inner diameter corresponds to the outer diameter of the smooth cylindrical surface.
