- Shown is a drive system 7.2 with driven friction wheels 8, which enables the use of electric motors whose diameters correspond, for example, to three to four times the friction wheel diameter, without their vertical distance from each other must be larger than the motor diameter.
- the height of the installation spaces for the drive system 7.2 can thus be minimized. This is achieved in that the electric motors 30.2 of the friction wheels 8 acting on the one guide surface 5.1 of a guide rail strand 5 are arranged offset by approximately one motor length in the axial direction of the electric motors compared to the electric motors of the friction wheels acting on the other guide surface 5.1.
- FIG. 4B where it is also shown that the electric motors 30.2 are preferably of relatively short construction and have relatively large diameters. With large motor diameters, the required drive torques for the friction wheels 8 are easier to generate.
- 5A and 5B show a self-propelled construction phase elevator car 4 which is very similar in function and appearance to the construction phase elevator cars shown in FIGS. 3A, 3B and 4A, 4B. The height of the installation spaces for the drive system 7.3 and thus the total height of the construction phase elevator car is reduced in this embodiment, however, by using smaller drive motors for the friction wheels 8.
- hydraulic motors 30.3 instead of electric motors to drive the friction wheels 8.
- Hydraulic motors can therefore also be used to drive friction wheels with larger diameters, which allow a higher contact pressure and can therefore transmit a higher traction force.
- Hydraulic drives require at least one hydraulic unit 36, which preferably comprises an electrically driven hydraulic pump.
- a hydraulic pump driven by an electric motor with a constant speed and having an electrohydraulically controllable delivery volume or one by means of
- Frequency converter speed-controlled electric motor driven hydraulic pump with constant delivery volume are used.
- the hydraulic motors are preferably operated in hydraulic parallel connection. Series connection is however also possible.
- the power supply to the hydraulic unit 36 takes place preferably via a conductor line, as was explained for the supply of the electric motors in connection with FIGS. 1 and 2.
- the construction phase elevator car 4 according to FIGS. 5A and 5B is also locked during a standstill by holding brakes 37 in the elevator shaft, the drive torques exerted by the hydraulic motors 30.3 on the friction wheels 8 being at least reduced.
- FIG. 6 shows a part of a drive system 7.4 of this construction-phase elevator car arranged below the car body 4.2 of a self-propelled construction-phase elevator car. An arrangement of a group of several is shown
- Drive motor 30.4 driven by a gear transmission 38 with two counter-rotating drive chain wheels 38.1, 38.2 and by a mechanical transmission in the form of a chain transmission arrangement 40.

- Triple chain sprocket 40.6 by means of a fifth chain strand 40.5 to a triple chain sprocket 40.7 arranged underneath and mounted on the fixed pivot axis of the lowest pivot lever 32.3. From this triple sprocket 40.7, the rotary movement is transmitted by means of a sixth chain strand 40.6 to a sprocket fixed on the axis of rotation of the lowest friction wheel 8.2 and thus to the friction wheel 8.2.
- the part of the chain transmission arrangement 40 shown on the right side of the drive system 7.4 is arranged essentially symmetrically to the above-described part of the chain transmission 40 shown on the left side of the drive system 7 and has the same functions and effects.
- This construction phase elevator car 54 comprises a car frame 54.1 and a car body 54.2 mounted in the car frame with a car door system 54.2.1.
- the car frame 54.1 and thus also the car body 54.2 are guided over guide shoes 54.1.1 on guide rail strands 5, which guide rail strands are preferably fastened to walls of an elevator shaft.
- Drive system 57 for the construction phase elevator car 54 serves at least one electric linear motor, preferably a reluctance linear motor, which linear motor has at least one primary part 57.1 fastened to the car frame 54.1 and at least one extending along the travel path of the construction phase elevator car 54 on
- the construction phase elevator car 54 is equipped with a drive system 57, which on two sides of the construction phase elevator car 54 comprises a reluctance linear motor, each with a primary part 57.1 and a secondary part 57.2 ,
- a reluctance linear motor each with a primary part 57.1 and a secondary part 57.2
- Each primary part 57.1 contains rows of electrically controllable electromagnets, which are not shown here, arranged on two sides of the associated secondary part.
- the secondary part 57.2 is a rail made of soft magnetic material which has protruding areas 57.2.1 on both sides facing the electromagnets of the primary part 57.1 at regular intervals.
- linear motor principles can be used as a drive system for a self-propelled building-phase elevator car, for example also linear motors with a large number of permanent magnets arranged along the secondary part as counterpoles to electromagnets controlled in the primary part with changing current strength.
- Reluctance linear motors can, however, be implemented at the lowest cost in self-propelled construction phase elevator cars with a large usable lifting height.
